With the use of Instron Universal Testing Machine, the mechanical properties of eggshells were determined and related to current handling and transport practices in the farm. Compression tests showed that bio-yield and rupture points were higher for jumbo and large eggs, respectively. Round eggs of these sizes had higher rupture point than slender eggs under transverse load. Similarly, round eggs of these sizes had higher deformation or rupture point under axial load. Strong correlation was found between eggshell thickness and rupture point under axial load but not under transverse load. Based on these results, modifications were adopted by Batangas poultry farms to minimize damage on poultry eggs based on current handling and transport practices.
